We can quantify the changes between humans, and our closest living relative, the chimpanzees. Our DNA is ~96% similar; there are an estimated 40 million differences between the genomes.

...

As for the estimate that only 10-20 mutations were beneficial, that scales up to nearly 700 beneficial mutations for humans in the same number of generations (or roughly one million years).

Let me guess... you think you found a contradiction?

The mechanism of evolution is change in DNA. That's all. The changes don't have to be beneficial, and most of them aren't.
